We just upgraded one of our SQL servers (we did a fresh format from Server 2008 R2 to Server 2016 and went from SQL 2005 SP4 to SQL 2017. We have SQLSafe 126.96.36.1999 with the license key update installed. SQLSafe Management Console sees the server but every backup fails with:
Server instance: MIAMI, Database: WWWSites
BTW, SQL Safe's services are running under the same domain\username as SQL Server and SQL Agent (the account has both local and domain admin rights). SQL Safe uses the SA username and pwd to access the server. I have logging enabled and am happy to post that too if that would help.
I had the same issue when backing up a SQL 2017 Instance. Make sure you have the latest CU installed on the 2017 server. I think the issue was resolved with CU4 but I went ahead and installed CU10 and have not had any issues.
CU10 fixed it! Thanks!
